Package Hackage Nightly LTS
Color Hackage Nightly Nightly

A library for dealing with Colors and pixels. It implements arbitrary color space conversion, chromatic adaptation and other color manipulations.

There is a clear separation between color models, color spaces and alternative representations of color spaces. All are distinct at the type level. The goal is to prevent mixups of incompatible color types as well as utilize type information for conversion between them.

Currently supported:

  • Color models:

    • Y
    • RGB
    • HSI
    • HSL
    • HSV
    • YCbCr
    • CMYK
  • Color spaces and arbitrary conversions between them:

    • Y - luminance

    • CIE XYZ

    • CIE L*a*b*

    • RGB:

      • sRGB

      • AdobeRGB

      • ITU: Rec470, Rec601 and Rec709

      • Alternative representations:

        • HSI
        • HSL
        • HSV
        • YCbCr
        • CMYK
  • Illuminants:

    • CIE1931 - 2 degree observer
    • CIE1964 - 10 degree observer
    • Some common alternatives
  • Chromatic adaptation:

    • VonKries adaptation with transformations:

      • VonKries
      • Bradford (default)
      • Fairchild
      • CIECAM02
  • Color Standards:

    • RAL
